Hi I tramp a lot with my 11 your old son – it’s a great reality check for him and he enjoys it: Pack, sleeping bag, tent or shelter, sleep mat, stove, billy, cup, bowl, water bottle than can be easily filled in rivers, water bladder for in pack, water treatment if you feel the need, spoon, swiss army knife (with scissor), rain jacket, (rain pants if forecast looks av) fleece, down jacket (dry/warm if its gonna be cold), 1 poly top, poly bottom, 3 pair socks, shorts, light weight hiking shirt x 2, wool singlet, beanie, sun hat, gloves, trail runners for summer, boots for winter/alpine. Clothing list really depends on weather forecast and time of year – and working on the premise that you should have something warm/dry to change into when you reach your hut or shelter. Then you dry off your wet stuff for the next day - Then food and med kit etc. Muesli/Milk Powder Breakfast, 8 Grain Crackers, Salami Cheese Lunch, Kaweka and CousCous or Back Country Dinner, Snacks (nuts/choco), 1 protein bar per day, Replace Sachet if you sweat a lot And if going off track navigation, maps, GPS, compass and hire PLB – Oh and Kitchen Sink.... Macpac, Bivouac, Kathmandu, Hunting and Fishing – have all the gear you could want - or Shop Online USA - cheeper – I have found though that your gear list evolves as you tramp, meet other people share ideas and experience the outdoors – and with an increasing desire (for me anyway) to shave weight where possible :)
